What are the steps to drain the radiator? What are the steps to drain the radiator?

Prepare a container that is packed, such as a bucket or tray, to prevent water from flowing into the pipes to the ground. Then find the location of the inlet and outlet valves, close them, open the water opening valve, and place the prepared poke or basin at the outlet to receive water. Finally, when the water is free of foam, the drain valve can be closed.

Heating refers to the supply of heat to the building and maintains a certain indoor temperature, which is a social service to solve the basic living needs of residents in northern China for winter heating.

Material tools: buckets or basins.

Step 1: Make sure to close the main valve of the radiator, this is to prevent the water from being released from the return pipe when the radiator is discharged, and prepare a bucket or basin for filling water.

Step 2: Take out the prepared bucket and put it under the drain valve, open the water release valve to connect the water in the radiator, and all the other valves need to be closed.

Step 3: Remember to close the outlet valve when the bucket is filled with water. When there are not many bubbles, it proves that the water on this side is exhausted, and you can open the other drain valve, according to this operation, repeat several times to release the air and water in the radiator.

The specific steps are as follows:

1. Close the inlet and return valves of the radiator, so as to control the water of the entire radiator in your home.

2. Start to release water from the bathroom, one is to solve the phenomenon of water spraying, so as to be more hygienic, and the other is that the heating of the general bathroom is the end, and the drainage is more convenient.

3. After the water in the heating is almost placed, you need to prepare a large air pump, and you need to use the air pump to blow out the residual water inside, after all, the patch will rust in a humid air.

Before the radiator discharges water, it is necessary to close the main valve, and then break the switch to the direction perpendicular to the radiator pipe, so as to avoid releasing the water in the return pipe when discharging water, and must let experienced people operate, because the water in the radiator has a certain temperature.

Close all the valves, only one valve can be opened, and after this step is completed, you can use a water pipe to connect the exhaust valve, and put the other end into the basin, and then open the drain valve, the water flowing out will enter the basin, and wait until the bubbles become less to prove that one side of the water has been discharged, and then open another drain valve, and operate in turn, and all the water and gas can be released.

The steps for waterproofing radiators are as follows:

Tools: heater, radiator, towel, screwdriver, basin.

1. Close the valve: You must first find the main return valve of the heating at home and turn it off, and then find the branch water inlet valve and turn them off one by one. When closing the valve, if the heating valve is a handwheel or ball valve, usually there will be an auspicious O letter on the surface of the valve, and there is an arrow mark near it, and there is an S letter and an arrow mark.

You can turn the valve in the direction of the arrow with the letter S to close it.

2. Prepare for water discharge: We will open the water supply valve of the radiator branch that needs to be discharged, and then we will prepare towels, screwdrivers and other related tools, and put the water basin under the radiator release valve.

3. Radiator drainage: The radiator release valve is a screw-shaped banquet switch, after we find the vent valve, first unscrew the safety of the vent valve, then hold a towel in one hand to pad it under the vent valve, and use a screwdriver with the other hand to gently unscrew the vent valve screw a little bit, and the vent valve will have water outflow.

Tips for using radiators

1. The temperature setting should be scientific: for customers who have just started to use the heating season, they can set the heating wall-hung boiler to a higher temperature, and then lower the temperature setting of the boiler after the indoor temperature rises to a stable level.

2. Indoor thermal insulation should be done well: the heat loss in the winter room 40 is related to the insufficient sealing of doors and windows, especially in families who are more accustomed to opening windows for ventilation. When decorating, the walls are made of good insulation materials, the doors and windows are equipped with sealing strips, and the windows are equipped with double-layer or insulating insulation glass, which can enhance the thermal insulation of the house and reduce heat loss.

Do a good job of indoor insulation, and the radiator system can also play a certain energy-saving effect when it is running.

Dear, I'm glad to answer your <>

Answer: How to release water from the radiator is as follows: The method of draining water from the radiator is as follows:

1.Close the valve: Before discharging water, be sure to close the water supply and return valve in the pipe well.

2.Disassemble the plug: Remove the plug and finally drain the water in the radiator.

3.Use an air pump: Use the same method to drain the water from the radiator in the pants.

4.Precautions: When the user transforms the heating, try not to change the pipes, and the direction of the heating equipment gives priority to the direction of the original radiator.

Abstract: What to do if the heating at home is not hot, the first thing that many residents think of may be to vent the radiator and release water. We may find that there are not a few residents who put water on the heating every other day, and many residents even put water once a day.

How do you put water out when the heating is not hot? Will the heating heat up? This requires attention to the following heating and deflation techniques.

1. Is it useful to drain water if the heating is not hot?

1. If the heating is not hot, do not blindly discharge water.

The main problem with unheated heating is the accumulation of air in the pipes, which leads to poor water circulation. When residents release water to the radiator, the water released from the radiator is actually gas, and the amount of water released is very small, some residents do not understand, and release a large basin of water, which not only wastes water, but also makes the heat source water in the heating pipe not stored enough, resulting in the heating can not reach the due temperature.

There are many reasons why the radiator is not hot, and the water can not be released without authorization, if the water is released without authorization, it will lead to the loss of water in a certain link in the system, resulting in the change of the pressure of the heat supply and clearing system, and the loss of a large amount of hot water in the pipe network, which leads to the radiator becoming less and less hot.

In addition, the water in the radiator has high temperature and high pressure, and it also contains chemicals that are harmful to the human body, so it is best not to let the water in the radiator out of the radiator at will.

2. The key to whether the heating is not hot depends on degassing.

If the heating in the home is not hot as a whole, it may be due to the outdoor water inlet and return valves are not opened; Locally not hot, possibly due to the fact that the top layer is not outgassed; The radiator is half flat and half hot and half cool, and the tail gathers air. Generally speaking, under the condition of ensuring the circulating pressure and temperature, the main reason why the heating is not hot is the air blockage, and the cohesive gas in the pipe can be released.

Second, how to properly drain the radiator.

The specific method of venting the heating is as follows: there is a manual exhaust valve on each radiator, the user can gently loosen the manual exhaust valve, and immediately stop twisting the exhaust valve when he hears the exhaust sound, and if there is a stable flow of water out, the exhaust valve can be gently tightened. After exhausting, if the radiator is still not hot, you should ask a professional to find out the cause and help solve the problem, and do not blindly discharge water.

The correct way to drain the radiator is as follows:

1. The main return valve of the heating needs to be closed, which can prevent the water in the return pipe from being further discharged. Turn off all water valves inside the heater and open the water supply valve for the valve that needs to drain the water.

2. Connect the water pipe to the exhaust gas outlet next to the water supply valve, and then put the other end of the water pipe into the basin, which can prepare for the drainage work.

3. Open the exhaust valve and wait for the water inside to stay from the drain pipe to the water basin. When you see water flowing out of the water mill pipe, close the drain valve after 3 to 5 seconds, and then close the branch water supply line valve. At this point, the drainage work has been completed.

4. If there are multiple rooms that need to be drained, open the branch water supply valve that needs to be drained, and then follow the above steps to release the water.

5. When all rooms have been emptied of water, it is necessary to open the water supply valves of all branches, and then open the main return valve, so that the heating can circulate normally.

What is a check valve:

There are two types of check valves, one is straight-through and the other is right-angle. The straight-through check valve is threaded and installed on the pipeline. There are three types of right-angle check valves: threaded connection, plate connection and flange connection.

Radiator heating check valves, also known as latching valves or pressure holding valves, are the same as check valves and are used to prevent oil from flowing in the opposite direction.

However, when it is necessary to negotiate the reverse flow of heating water in the heating circuit, the heating pressure can be controlled and the check valve can be opened to make the heating water flow in both directions.
